These are online communities which provide an opportunity for people with a common experience (such as a condition or disease, or a care-giving role) to share their concerns, and to seek and provide information and advice. Message boards, mailing lists, and moderated forums may be found here, as well as general chat rooms and forums.

Sites listed here will represent support groups which exist only on the Internet. If the group has a physical address or meeting place as well, the site should be submitted to the appropriate Support Group category, as well as to the relevant Regional subcategory. Submissions by registered support charities should be submitted to the appropriate Support Group category.
